DETAIL DESCRIPTION OF THE INVENTION

FIG. 4 is a perspective view of a structure of a holding mechanismaccording to an embodiment of the present invention. Referring to FIG.4, the holding mechanism comprises a pressure-bearing unit 21, abuckling element 22 and an operating assembly 23. The operating assembly23 comprises a bidirectional knob 231, a protrusion member 232 and anaxle 233. The buckling element 22 and the pressure-bearing unit 21respectively comprise the positioning portions 211, 221. Thepressure-bearing unit 21 comprises an opening 212 for receiving themovable buckling element 22.

FIG. 5 a perspective view showing while securing the buckle holdingmechanism on the radiator. Hereinafter, the assembly of the holding 20mechanism may be described with reference to FIG. 4 and 5. The bucklingelement 22 is first penetrated through the opening 212 of thepressure-bearing unit 21 to let the axle 233 penetrate through the axlehole 221 a of the buckling element 22 and the through hole 232 a of theprotrusion member 232 to securely position the buckling element 22 intothe receiving portion 231 a of the bidirectional knob 231. The axle 233is disposed into the axial hole 221 adopted for pivotally engaging theoperating assembly 23 to the buckling element 22.

According to an embodiment of the present invention, the assembly ofholding mechanism to secure the radiator may be described as follows.

First, the components of the holding mechanism may be dissembled. Next,as shown in FIG. 6, the radiator 25 is disposed in the chassis 24 andthe positioning portions 211 and 221 of the buckling element 22 andpressure-bearing unit 21 respectively are buckled onto the two bucklingblocks 241 that are formed protruding from two sides of the chassis 24,wherein the lower portion of the protrusion member 232 protrudes upwardsand the buckling element 22 is positioned at the lowest part thereof.

Next, referring to FIG. 7, when the user turns the bidirectional knob231 towards the left direction or anti clock direction, the side 232 cof the protrusion member 232 supports against the pressure-bearing unit21 to move the buckling element 22 move upwards, the lower portion 232 dof the protrusion member 232 is moved towards the left, and the bucklingelement 22 is positioned at the middle part.

Next, referring to 8, the bidirectional knob 231 is continuously turnedanti clock direction, the side 232 c of the protrusion member 232correspondingly slides towards the right direction towards the side 232c of the protrusion member 232 supported against the pressure-bearingunit 21, and the buckling element 22 also gradually moves upwards, thelower portion 232 d of the protrusion member 232 gradually facesdownwards, and the buckling element 22 is positioned at the middle part.

Next, referring to FIG. 9, when the upper side of the protrusion member232 is completely facing upwards, the positioning portions 211 and 221of the buckling element 22 and the pressure-bearing unit 21 are tightlysecured to the buckling block 241 of the chassis 24, and the supportingportion 213 at the middle part of the pressure-bearing unit 21 alsopresses down to securely hold the radiator 25.

FIG. 10 is an exploded view of a holding mechanism according to anotherembodiment of the present invention. Referring to FIG. 10, the operatingassembly 26 comprises an axle 263, a protrusion 262 and a bidirectionalknob 261. The distal end of the bidirectional knob 261 is adopted forthe user to hold, and the primal end of the bidirectional knob 261comprises a protrusion 262. The protrusion 262 comprises an axle 263. Toassemble the operating assembly 26, the axle 263 of the operatingassembly 26 is inserted into the axial hole 221a of the buckling element22. Thus, the above simplified structure can be manufactured a lowercost.

Accordingly, the present invention has at least the followingadvantages.

1. The holding mechanism of the present invention comprises thebidirectional knob to support the protrusion member against thepressure-bearing unit to move the buckling element on thepressure-bearing unit, and therefore the possibility of damaging theholding mechanism due to different operations thereof or usage ofexcessive force may be effectively reduced.

2. The bidirectional knob can be rotated either clock wise or anti clockwise without limiting the rotation direction.

3. The coupling moment while rotating the bidirectional knob may be usedso that the bi-directional knob may be rotated applying comparativelyless force.
